采用化学接枝马来酸酐对碳纤维进行表面处理。利用FT-IR、TG及Raman等手段,对表面处理各阶段碳纤维的结构进行表征。结果表明马来酸酐接枝后的红外光谱在1722cm-1处出现CO伸缩振动的特征峰;接枝马来酸酐的碳纤维的热失重率为2.729%,接枝法能使碳纤维表面接枝上更多的含氧官能团;拉曼光谱表明碳纤维表面的微晶尺寸减小,石墨微晶边界的活性提高,有利于提高碳纤维与树脂间的粘结性能。
The chemical grafting maleic anhydride onto carbon fibers were adopted.The surface microstructures of carbon fibers treated with various stages were characterized by FT-IR,TG-DSC and Raman.The results indicated that the carbonyl groups were appeared in the infrared spectra;the thermal weightlessness rate was 2.729% after grafting MAH.More oxygen-containing function groups can be grafted onto the surface of carbon fibers by the modification with grafting.The Raman spectra showed that the crystallite size was reduced,and the activity of the graphite crystallite boundary was improved,which may be of great benefit to the improvement of the bonding properties between carbon fibers with resin.
